The divested assets include 30,821 net acres in Pecos county and 1,361 net acres in Reeves county of Texas, according to the company.

Whiting Petroleum chairman and CEO James Volker said the sale is expected to increase liquidity to accelerate development of Williston Basin and DJ Basin Niobrara assets.

"In addition, this transaction will bring a new operator to the area whose drilling we expect will help de-risk our remaining 41,173 net acres at Big Tex, which is composed of 30,846 net acres in Pecos County, Texas, 6,207 net acres in Reeves County, Texas and 4,120 net acres in Ward County, Texas," Volker added.

The company has oil and gas assets in Rocky Mountain, Permian Basin, Michigan, Gulf Coast and Mid-Continent regions of US.
